Specification of Letters Patent.

Patented Mar. 7, 1911.

Application filed June 24, 1910. Serial No. 568,667.

T 0 all whom it may concern:

Be it known that I, Josnrr-r Juno, a citizen of the United States, residing at Elizabeth, county of Union, State of New Jersey, have invented an Improvement in Oiling-Boxes for Rolling-Mills, of which the following is a specification.

This invention relates to oiling boxes for rolling mills and is an improvement upon my former Letters Patent Number 499,431, dated June 13, 1893.

It is one of the objects of the present invention to provide improved means for saving, clearing and straining all oil that may drop "from the rolls so that there will be no loss of oil-except what actually adheres to the metal that is being rolled.

A further object of the invention is to provide convenient means for shifting from an oiling box to a dry box and vice versa in an instants time and without drawing off any of the oil or water.

A further object of the invention is to provide convenient means for adjusting the side plates to the width of the coils of metal to be rolled.

lVith these and other objects in view I have devised a novel oiling box which I will now describe, referring to the accompanying drawings forming a part of this specification and using reference characters to indicate the several parts.

Figure 1 is a view partly in elevation and partly in section on the line 11 in Fig. 3 of my novel oiling box complete; Fig. 2 a plan view of the oil receptacle detached; Fig. 3 a section on the line 33 in Fig. 1 showing the rolls and oil cup; and Fig. 4 is a plan view of the coil holder detached.

1O denotes the rolls, 11 the oiling box and 12 a coil of metal that is being rolled. The coil which is ordinarily wound upon a drum or block 13 rests upon a holder 14 which consists of a strip of metal suspended from cross pieces 15 which extend from side to side of the box. In practice I provide a single cross piece at one end of the box and two cross pieces at the other end, one above the other. The ends of the holder are curved over and downward to engage the cross pieces. When the box is used as a dry box, the coil is raised above the surface of the oil and water in the box by suspending the holder from the upper of the two cross pieces, as shown in full lines in Fig. 3, and when the box is used as an oiling box the holder is suspended from the lower of the two cross pieces, as shown by dotted lines in Fig. 3,

which causes the immersion of the lower side of the coil in the oil and water. A slot 16 at the mid-length of the holder provides drainage for the oil and water when the adjustable end of the holder is shifted from the lower to the upper cross piece. In order to protect the sides of the box and to provide for the winding of narrow coils as well as wide ones, that is to hold narrow coils up right and to separate narrow coils when a plurality of coils are wound at a time, I provide loose side plates 17 which are retained in place by dropping the ends thereof into slots 18 in the holder, the slots being ar ranged in pairs in alinementwith each other on opposite sides of central drainage slots 16. The way in which the side plates are held in place will be readily understood from Fig. 3. They are simply dropped into the slots and rest upon the bottom of the holder, which is specifically indicated by 2-0. I have found in practice that the metal passes from the coil to the rolls more evenly and smoothly and surplus oil and water are removed therefrom by passing it over cross rods 19. I therefore provide detachable extensions 21 which project above the sides of the box and in which the cross rods are rigidly anchored. The lower ends of the extensions are provided with tenons which engage suitable cleats or holders 22 on the sides of the box. If not required in use, the extensions and cross rods may be removed and as readily replaced when required.

The oil and water that drips from the rolls is caught in a cup 23 carried by an inclined conductor 24 which extends upward from the box into which it opens above the oil and water line. The bottom of the cup is a concave curve in cross section and the conductor leads therefrom at a distance above the bottom, thereby providing a pocket 25 in which the heavier portion of the dustand dirt settles, so that the oil and water that passes from the oil cup back to the box is partly cleaned through the deposit of sediment.

26 denotes an oil receptacle, the bottom of which is placed below the level of the bottom of the box. An escape pipe 27 leads from the box to the oil receptacle entering the oil receptacle near the top thereof and leaving the box at suflicient distance above the bottom thereof to retain the desired oil and water level in the box, which is indicated by 28. lVithin the box, pipe 27 extends downward the opening being near the bottom of the box so as to minimize the passage of oil therefrom.

In Fig. 1, have shown an oil receptacle adapted to ope ate in connection with two oiling boxes and sets of rolls, two pipes 27 being shown as leading into it. The water from pipes 27, which usually carries moi'e or less oil with it, drips into receiving compartments 29 in the receptacle. Pipes 30 which open near the bottom of the receiving compartments extend upward, pass through the walls of the receiving compartments and open into straining compartments 31. It will be obvious that more or less water passes to the receiving compartments with the oil. In these compartments the oil sepa rates from the water and the impurities separate themselves from the oil and drop down through the water to the bottom. It is desired that as little oil as possible should pass from these compartments until enough oil has collected therein to force all the water out, then oil will pass out through pipes 80. At the center of the oil receptacle is a storage compartment 32 into which the oil passes from compartments 31 through removable vertical filters 33. A pipe 34 opens near the bottom of compartment 32, extends upward and passes out through the wall near the top thereof. By the time the oil has reached the storage compartment it will be thoroughly separated from the water. As pipe 34 extends nearly to the bottom of this compartment it will be obvious that only water can pass therefrom through said pipe. At a distance below the upper end of pipe 3% is an oil cock 35.

The operation is as follows: ater is either poured into the box when required or a small quantity of water is kept flowing into it. Oil is also poured into the box or sup plied to it in any suitable manner, the oil of course rising to the surface of the water. The relative quantity of oil and water in the box, within reasonable limits, is immaterial so far as the principle of the invention is concerned. It is obvious that surplus water will pass out from the box through pipe 27, thus maintaining the oil and water level. Both oil and water are taken up by the strip of metal and pass -'to the rolls, a portion of the oil and water being removed by cross rods 19, when used, and dripping back into the box. The oil and water which drips from the rolls is caught by the cup, where a certain amount of settling takes place, and from the cup passes back to the box through conductor 24. WVater from the box, carrying usually more or less oil with it, passes from the box to the receiving compartment of the oil receptacle, from which it passes through pipe 80 to the straining compartment. As the passage of water and oil from the receiving compartment to the straining compartmentis slow, all of the heavier sediment will settle in the bottom of the receiving compartment. In passing from the straining compartment to the storage compartment, the water and oil must pass through filter 83 which removes therefrom the finer portion of the dust that has not been precipitated in the receiving compartment. As the filters simply slide in ways 36 they may be readily removed for the purpose of clearing them of sediment. 'Water is free to escape from the storage compartment through pipe 34- but owing to the fact that the inner end of the pipe extends nearly to the bottom of the compartn'ient no oil can pass out with it. Cock 35 is provided in order to draw oil from the storage compartment for use.

Having thus described my invention I claim:

1. A box of the character described having means for preserving the oil and water level, a coil holder suspended therein and means for adjusting the coil holder so as to place the bottom thereof above or below the oil and water level to provide either an oiling or a dry box as may be required.

2. A box of the character described having means for preserving the oil and water level, a cross piece at one end thereof, a coil holder one end of which engages the cross piece and two cross pieces at the other end of the box either of which is adapted to be engaged by the corresponding end of the coil holder so as to place the bottom of the coil holder either above or below the water and oil level, for the purpose set forth.

8. A box of the character described having means for preserving the oil and water level, a coil holder suspended therein and provided with slots in line with each other on opposite sides of the center and side plates adapted to engage said slots, for the purpose set forth.

4. A box of the character described having means for preserving the oil and water level, a coil holder having a drainage slot and on opposite sides thereof slots in line with each other, side plates engaging the last mentioned slots and means for adjusting the height of the coil holder at one end.

5. An oiling box having means for pre serving the oil and water level, a cup having a concave bottom, for the purpose set forth, and a conductor by which the cup is supported and Which leads therefrom at a distance above the bottom and connects with the box.

6. The combination with an oiling box having means for preserving the oil and Water level, and a coil holder suspended] tachably connecting the extensions to the sides of the box.

In testimony whereof I afiix my signature in presence of two Witnesses.
